M-CogScore versus Clinical Dementia Rating and Mini-Mental State Examination: a comparison study

  • Clinical Dementia Rating (CDR) and Mini-Mental State Examination (MMSE) are commonly used to test mild cognitive impairment (MCI); however, recently there has been a need for remote testing requiring minimal time and supervision.  
  • Following a head-to-head comparison with CDR and MMSE, the digital screening test (M-CogScore) significantly correlated with impaired cognition on CDR (P<0.001) and MMSE-2 (P<0.0001). Additionally, the area under the receiver operating characteristic curves (AUC) was 0.85 compared to an AUC of 0.78, when differentiating between normal and impaired cognition.
  • According to the authors, M-CogScore is more effective for rapid and remote testing of cognitive function when compared with the CDR and MMSE tests.
